A virtual data room (VDR) is an online secure platform that allows you to share documents with different parties during M&A due diligence, M&A, and other financial transactions. VDRs offer a variety of features which can make them more valuable to dealmakers than cloud storage tools and other document sharing apps. They also focus on security, which makes them an ideal choice for sensitive business data as opposed to consumer cloud services that come with low security measures.
Storage virtualization is the layer of abstraction that software provides between physical storage devices and applications. It allows for the more efficient and flexible use of storage resources by reducing hardware redundancy requirements and facilitating data migrations, and streamlining advanced storage management features like snapshots and replication. It also helps reduce costs by eliminating the need to forecast future storage requirements, pay for all needed capacity in advance or purchase and maintain multiple appliances in order to meet the demands of growth.
The most commonly used storage that is virtualized is the network-based virtualization. It takes a http://www.virtualdataspace.biz/what-is-a-bolt-on-acquisition/ pool of storage, such as disks in a Fibre Channel (FC) or Internet Small Computer System Interface (iSCSI) storage area network (SAN), and presents it to applications and servers over the network. It makes use of redundant arrays independent disks technology (RAID) to improve performance and safeguard data in the case that one drive fails. However, the physical location of the disk and the individual hardware are hidden from the application and users.
Storage virtualization through arrays is the next step. A storage controller is employed to combine the storage of multiple arrays into a single pool and present it to applications. This allows enterprises to use more cost-effective storage tiers that may include solid-state drives and hard disk drives with varying capacities, and conceal the physical location of these various kinds of storage from both servers and users.
